Specification of Letters Patent.

Patented Feb. 12, 1907.

Application filed July 3,1906. erial No. 324,605.

To (DZ/Z whmn it may concern.-

Be it known that I, RAMoN F. CORDERO, a citizen of the Republic of Venezuela, and a resident of Rubio, in the State of Tachira, Venezuela, have invented a new and Im proved Drier, of which the following is a full, clear, and exact description.

This invention relates to improvements in driers for coffee, cereals, fruit, &c., an object being to provide a device by means of which the material may be rapidly and thoroughly dried.

I will describe a drier embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan v1ew of a drier embodying my invention. Fig. 2 is a sectional elevation thereof. Fig. 3 is a longitudinal section. Fig. 4 is an end elevation. Fig. 5 is a section on the line 5 5 of Fig. 6. Fig. 6 is a transverse section of the lower portion of the drier. Figs. 7 and 8 are perspective views of receiving-troughs employed. Figs. 9, 10, and 11 are detail views showing the different positions of a feeder employed. Figs. 12, 13, and 14 are detail views showing the air-distributing pipes employed, and Fig. 15 is a sectional elevation showing the device as ar ranged for drying fruit or the like.

In the drawings I have shown two driers A B, arranged side by side. It is to be understood, however, that in practice a greater number may be employed. Each section comprises a casing having side walls 10 11 and end walls 12 13. The front end wall 12 of each section is provided with a door 14, so that the fruit-supporting shelving may be placed therein, as will be hereinafter described.

Arranged inward of the wall 10 andspaced therefrom is a perforated wall 15, and inward of the wall 15 and spaced therefrom is a perforated wall 16. At the opposite side are similarly-perforated walls 17 18. The coffee or other material to be dried is to pass downward between these perforated walls, as will be hereinafter described, and in the passage between said walls the material will be met by a C1ICL1l2MI1OIl of air heated to a suitable degree. The perforated walls 15 and 17 are supported by strips 19, attached to the outer walls 10 11, so as to stiffen the said perforated walls and prevent their warping under heat. It may be here stated that these perforated walls may consist of wire-cloth.

Inward of the walls 16 18 are plates 20, consisting of iron or other suitable material, and these plates 20 are held removably in place by means of hooks or clips 21, attached to bars 22 and extended over the upper edges of said plates, while the lower edges of the plates engage with clips 23, attached to bars 24. These plates 20 are designed to prevent the passage of hot air to the middle portion 01 the drier-section when the drier is used forcoffee, cereals, or the like.

In the upper portion of each section are deflectors 25 26 for directing coffee or the like to the space between the perforated walls, and the material is directed to these deflectors of opposite sections of the drier by means of swinging deflectonboards 27, which are adjusted as to their angle by means of screws 28. The said boards 27 are hinged to inclined boards 29, onto which the material is discharged from a tube comprising a semicircular fixed section 30 and a semicircular section 31, designed to have a rotary motion.

At one end of the feeding device is a hopper 32, having an outlet 33 at one side, which is closed at a certain time by the end wall of the rotary section 31. To permit of an easy movement of this rotary section, it is arranged to operate on rollers 34, mounted in segmental tracks 35. At intervals cords or cables 36 are attached to the rotary portion of the feeder-pipe. These cables extend over pulleys 37 at one side of the frames 38 and connect with weights 39, and at the other side the said cords or cables extend over pulleys 40 and connect with weights 41. A spiral feeder 42 extends through the feeder pine or tube, and on the rear end of the shaft thereof is a band-wheel 43, driven from a pulley 44 on the shaft of the drivingwheel 45. This band-wheel 43 is provided with a tooth 46, designed to engage with a toothed wheel 47 to impart a step-by-step rotary movement thereto. The shaft 48, to which this toothed wheel 47 is attached, extends lengthwise of the drier, and it is pro vided with fingers 49, designed to engage with the weights 4]., raising said weights and permitting the weights 39 to rotate the section 31 of the feeder, thus causing an opening between the lower edge of said rotary section 31 and the fixed part or feeder 42, whereby the coffee or other material will fall upon the boards 29.

In Fig. 9 the parts are shown in a position for discharging the coffee or other material into the tube.

Fig. 10 shows the rotary part as moved to one-half of its movement, and Fig. 11 shows the said part as wholly moved, closing the outlet 33 and causing an opening for the discharge of material.

Arranged in the lower portion of each drying-chamber and lengthwise thereof is an air-conductor pipe 50, having openings or ports 51 at intervals, through which the air may be discharged against the top wall 52 of a receiving-hopper 53, and from this top wall 52 the air is deflected to the perforated walls, as indicated by the arrows in Fig. 2. The top wall of the conductor-pipe 50 is provided with downwardly-extended lugs or projections 54, designed to break up the air somewhat as it passes through the tube, and below the outlets or ports 51 is a deflectingrib'55. It will be noted in Fig. 2 that the hopper is arranged for receiving material from two sections of the drier, and this material is directed by the inclined bottom wall to a receiver-tube 56, in which is a spiral conveyer 57, designed to carry the material lengthwise of the tube and cause its discharge through a spout 58.

Arranged underneath the space between the perforated walls 15 and 16 is a series of troughs 59, which are shown as V-shaped in cross-section, and each has an opening at one side of its top, and a discharge-opening 61 is provided in one of the side walls, the said discharge-opening 61 being closed by a rail or bar 62, extended lengthwise in the hopper, said closing taking place, however, when the opening 60 is in line with the space between the walls 15 16. Similar receivingtroughs 63 are arranged underneath the space between the walls 17 18'. Extended through the hopper underneath the section A is a shaft 64, and a similar shaft ex tends through a portion of the hopper underneath the section B. On the shafts 64 65 are fingers 66, designed'to engage with fingers 67, extended outward from the lower portions of the receiving-troughs at one side, and these fingers 66 are also designed to engage with the receiving-troughs at opposite sides to tilt the same.

On the outer end of the shaft 64 is a gearwheel 68, and on the outer end of the shaft 65 is a gear-wheel 69. These gear-wheels are designed to be engaged one after the other,

so as to impart a step-by-step rotary movement thereto in order to tilt the troughs by means of a lug or tooth 70, carried on the periphery 0f the band-wheel 45. It may be here stated that the conveyer 57 is rotated by means of a band 71, engaging with a pulley on the shaft of the band-wheel 45 and with a pulley 72 on the shaft of the conveyer.

The several air pipes or tubes 50 communicate with an air-pipe 73 through off set-pipes 7 4. This pipe 7 3 communicates with a trunk 75, on one side of which is a chimney 76, and also communicating with this trunk 75 is a cold-air pipe 77, and within the pipe 77 is a hot-air pipe 78, which also communicates with the interior of the trunk 75 and leads from a furnace or heater 79. Near the heater end the said pipe 77 communicates with a casing 80, into which air is forced by a blower or fan 81,.and to prevent the cold air from striking suddenly against the hot-air pipe 78 and causing a warping or breaking I arrange a metal plate 82 underneath said hot-air pi e just above the opening for the inlet of co d air. The pipe 78 is supported at intervals by standards 83, and in the top wall of the casing is a flue 84, provided with a damper 85, which will automatically open ,under certain pressures within the pipe 77 and permit the entrance of atmospheric air. I Under a higher pressure, created by the fan 81, however, the said damper will be forced to closed position.

In the operation the mixed hot and cold air is forced through the pipes 77 78 and thence through the several ducts or passages 50, and this air, as before described, will circulate through the several perforated partition's and ultimately exhaust through the exhaust-pipes 86. At this time, of course, the material to be dried is passing down between the said perforated partitions and discharging into the troughs. As the shafts 64 65 rotate they will tilt the troughs having the fingers 67, causing the upper portions of the troughs to close the lower ends of the spaces between the perforated partitions and removing the openings 61 from the bars 62, thus permitting the cofiee or other material to discharge into the hopper 53. The other troughs will likewise be engaged by the finger 66 and tilted to discharge material. For the purpose of drying fruit and the like I arrange in the driers frames for supporting shelves or trays (i as shown in Fig. 15. These frames may be of any suitable construction, but, as shown, each consists of uprights 87, a base-board 88, having rollers 92 -mounted thereon, and longitudinal rails 89,

upon. which are mounted rollers 90.

It is to be understood that when the drier is used for drying fruit or the like the several use; neither are the discharging-troughs brought into use.
